Abstract

A power outage confirmation device that confirms whether a power outage has occurred in an area including a communication building and a plurality of subscribed users accommodated in the communication building includes: a user confirmation unit that acquires information on the plurality of subscribed users in a case where a communication abnormality is detected from a power monitoring device; a subscription log confirmation unit that confirms a log of an in-home device of each of the subscribed users on the basis of the information; and a power outage determination unit that determines whether a power outage has occurred in the area on the basis of the log.

1 . A power outage confirmation apparatus configured to confirm whether a power outage has occurred in an area including a communication building and a plurality of subscribed users that are accommodated in the communication building, the power outage confirmation apparatus comprising:
 circuitry configured to
 acquire information on the plurality of subscribed users, upon occurrence of a condition in which a communication abnormality is detected by a power monitoring device; 
 confirm a log of an in-home device of each of the subscribed users based on the information; and 
 determine whether the power outage has occurred in the area based on the log. 
   
     
     
         2 . The power outage confirmation apparatus according to  claim 1 , wherein the circuitry is configured to determine that the power outage has occurred in the area in a case of confirming power-off logs in logs of in-home devices of subscribed users whose number is equal to or greater than a threshold within a time section, the subscribed users being included in the plurality of subscribed users. 
     
     
         3 . A power supply depletion confirmation apparatus configured to confirm whether a power source of a communication building is depleted, the power supply depletion confirmation apparatus comprising:
 circuitry configured to
 acquire information on a plurality of first transmission devices connected to a second transmission device in the communication building via one or more transmission paths, upon occurrence of a condition in which a communication abnormality is detected by a power monitoring device; 
 confirm communication from each of a part or all of the plurality of first transmission devices to the second transmission device in the communication building; and 
 determine whether the power source of the communication building is depleted based on a confirmation result of the communication. 
   
     
     
         4 . The power supply depletion confirmation apparatus according to  claim 3 , wherein the circuitry is configured to determine that the power source of the communication building is depleted upon occurrence of a condition in which the communication from all of the first transmission devices is not confirmed. 
     
     
         5 . A power outage confirmation method executed by a power outage confirmation apparatus that confirms whether a power outage has occurred in an area including a communication building and a plurality of subscribed users that are accommodated in the communication building, the power outrage confirmation method comprising:
 acquiring information on the plurality of subscribed users upon occurrence of a condition in which a communication abnormality is detected by a power monitoring device:   confirming a log of an in-home device of each of the subscribed users based on the information; and   determining whether the power outage has occurred in the area based on the log.   
     
     
         6 . (canceled) 
     
     
         7 . A non-transitory computer storage medium storing a program for causing a computer to execute processing as in the power outage confirmation apparatus of  claim 1 . 
     
     
         8 . A non-transitory computer storage medium storing a program for causing a computer to execute processing as in the power supply depletion confirmation apparatus of  claim 3 .
